2019-01-26 13:14:16 UTC - Yuvaraj Loganathan: When JsonSchema is Used to
produce messages , only the values of json fields are stored as part of
message or the whole message with all the keys and values are stored ?
Basically If JSONSchema is used , will the amount of storage used will be
reduced or not ?

set-retention --size -1 --time -1 public/default The response received is
```pulsar-admin namespaces get-retention public/default
{
"retentionTimeInMinutes" : -1,
"retentionSizeInMB" : 0
}
```

2019-01-26 14:14:35 UTC - Yuvaraj Loganathan: retentionSizeInMB always show 0
even though it is set -1. Is it a bug ?

2019-01-26 15:06:16 UTC - Matteo Merli: Just tried and seems to work for me:
```
$ ./bin/pulsar-admin namespaces set-retention public/default -s -1 -t -1
$ ./bin/pulsar-admin namespaces get-retention public/default
{
"retentionTimeInMinutes" : -1,
"retentionSizeInMB" : -1
}
```

2019-01-26 15:09:15 UTC - Matteo Merli: With JSON schema the objects are
serialized into standard JSON, that is with keys and values.
Typically, if you have a decent amount of batching of the messages and you
enable compression in the producer, that won’t be a big size overhead.
Though, if you want to have compact serialization, you should look into using
the Avro schema instead.
